Answer:
1. U. 190
2.U. 155
3. U. 240
Step-by-step explanation:
Explanation: To find an angle of a triangle we add the angles we know about
EXAMPLE: 50 + 120. We need to find the third angle.
We know that Angles of triangles should add up to 360
So to find the third angle we add the angle we know about.
EXAMPLE: 50 + 120 = 170 then we Subtract the sum of a triangle *360*
EXAMPLE: 50 + 120 = 170
EXAMPLE: 170 - 360
EXAMPLE: = 190
That's how we find a third angle!
If this doesn't clarify how do to it enough just let me know and i can try to explain more in detail!
Hope this helps you!!!
Have a nice day!
Answer:
Option D (2, 6)
Step-by-step explanation:
As shown in the graph function has four intervals on which graph is plotted.
1). From the graph we can see in the interval -10 ≤ x ≤ 0 graph is increasing.
2). From 0 ≤ x ≤ 2 function is decreasing.
3). Between 2 ≤ x ≤ 6 function is constant.
4). And for x ≥ 6 function is increasing.
Therefore interval in which the function is constant is (2, 6).
Two supplementary angles when added together need to equal 180 degrees.
Let the first angle = X
The second angle would then be X - 152
Add them together to equal 180:
X + X - 152 = 180
Simplify:
2X -152 = 180
Add 152 to each side:
2X = 332
Divide both sides by 2:
X = 332 / 2
X = 166
The first angle = X = 166 degrees.
The second angle = X - 152 = 166 - 152 = 14 degrees.
The angles are 166 and 14
Angle AOD and < BOD are supplementary since they are both right angles which equal 180°.
<h3>What is a supplementary angle?</h3>
It should be noted that a supplementary angle simply means an angle that adds up to 180°.
In this case, the angles given are both rights angles. This will be:
= 90° + 90°
= 180°
In this case, Angle AOD and < BOD are supplementary since they are both rights angles which equal 180°.

2/3 x 21 is correct because 21 is bigger than 15
